tests: Test pseudo-syscalls in the sim binary tree test

Now that pseudo-syscalls are being explicitly removed from
the resultant BPF filter, we need to test for this in the
simulated binary tree test.  This commit modifies the test to
explicitly define its supported architectures and updates the
tests file to handle PNR syscalls.
